Application filed March 4, 1915. Serial No. 12,074.

tuo s the use of multiple jet pip-es that are so disposed in the natural spaces of the boiler that jets of steam may be projected along and across and through botn sets of pipes and over the interior surfaces on Which the gases ombustion are liable to deposit soot, ash and other matter deleterious to invention relates to a soot blower or tube boils ha ing sets of pipes rrrunged in opposit l ur. relation and usually stagger crnuted in po'ition.

' co inthc matters here id more particularly oended claims. A 212"(3 l is :1 view section ucsoss .1 boiler of the t me led, equipped with a blower that em bodies :lfeaturcs of the invention; Big. 2 is a View in longitudinal section of the boiler, 11d Figs. 3 and lare views in detail of brackets for supporting blower units from the water tubes.

in the drawings, a boiler ,is illustrated having a pair of headers l and interconnected by water tubes 3 that are in alternate arrangement to another set of water tubes 4 of opposite inclination, which connect other headers 5 and 6. The headers are upprotel y connected to a steam dome 7 and l uns 8 or the like, and are arranged b setting 9 over tl l c ate bars l1 n vlil 'lll blower un l e edvantageously placed. In order to clean flue upper space effectively, a jet pipe 12 is extended across the boiler transversely to the the boil result jets tubes of both sets on which it is supported as by appropriate brackets indicated at 13. Such tubes have lateral jet openings or jet nozzles Li which may be of the Venturi blower type, and may as herein indicated be jacketed or incased with a heat protecting lining 15 and outer casing 16, or thejet pipe may be Water jacketed or air cooled or otherwise arranged to resist high temperature. At the ends, appropriate housings l9 and are employed that are mounted in r setting walls as bearings for the jet pipes, a steam pipe 21 leadingeither from. the boiler itself or some other suitable source of supply, (or it may be a line from a source of air under pressure) is connected through a suitable fitting 22 with the pipe while it wheel to which a sprocket chain may be applied as desired, affords means for turning the pipe in all directions. As a may be made to sweep across and along and between the tubes in the direction of length as well as transversely thereto while they may also be made to impinge against and between the surfaces that deii the passes of the boiler. In addi- I n to this pipe 12; other jet pipesmay be employed and such are shown at 26 and 27. These are simi ar in all respects to the pipe 12 and are mounted in a similar manner. ljt' course the upper units 12 may be left out and the lower unit only employed or all three may be used as herein shown.

As a. convenient means for supporting the pipes rotatubly on the wuter tubes, bearings which may be easily alined may be employed. As one preferred form, the bearing 13 which is shown in detail in Figs. 3 and 42 is used, in which a bridge member with compmr ion clip 2 span uv pair of water tubes, being retained by a clamping bolt 30. The member 28 has a pair of screw threaded studs 31 on which the half members 32 of a bearing are adj ustably secured between jam nuts 33, so tlmt they embrace the casing 16 of the boile to )8 l2.

t of this construction, a soot t readily cleans boilers l 1- willy mounted ease or adjustment of mg members and the utilization of mil spaces oi the boilers in which to place the tubes. The multiple jet effect sweeps the soot from all parts of the boiler and thereby avoids the necessity of use of the unwieldy hand blower and its inconvenience.

Obviously, changes in the details of conlique relation and a setting therefor, means disposed transversely to the tubes in the angular spaces formed between the sets and adapted to direct cleaning jets across, between and along the tubes of the sets adjacent the an gles and over the interior surfaces of the boiler.

2. In a boiler having obliquely disposed sets of water tubes in oppositely arranged,-

transverse relation, jetting means mounted at the angles formed by the oppositely dis osed sets and arranged to direct cleaning jets across and along and between the por-.

, tions of the tubes of the several sets adjacent the angles and against and over the interior surfaces of the boiler.

3. In a boiler having a pair of oppositely inclined transversely disposed sets of water tubes, jet pipes rotatably mounted at the angles formed by the sets and adapted to direct cleaning jets across and along and between the portions of the tubes of the sets adjacent the angles and the inclosing surfaces of the boiler.

4. In a boiler having a pair of oppositelyinclined transversely disposed sets of water tubes, means-for confining and directing the gases of combustion of the furnace of the boiler over the tubes, rotatable jet pipes in the angles formed between the tubes of the companion sets, means rotatably support-' ing the pipes on the water tubes, and means for manipulating the jet pipes for directing cleaning jets therefrom across,

along and between the portions of the water tubes adjacent the angles and the interior surfaces of the inclosing means.

5. In a boiler having inclined water tubes,

jetting means rotatably secured in operative relation to the pipes and means forming ing of a bridge member adapted to span a pair of water tubes, a companion clip therefor adapted to span a pair of water tubes, a clamping bolt securing the clip and bridge bearings for the jetting means each consistmember, bearing members embracing a jet pipe, and adjustable supporting means on,

the bridge member for the bearing members. In testimony whereof I aflix my signature in presence of two witnesses.
